1/2" tube adapter to 15 mm hose

John Guest adapter from 1/2" tube to 15 mm hose

Transition fitting to connect a 1/2" (12.7 mm) tube line to a 15 mm hose connection. Useful when an installation combines different pipe formats and a compact transition is required.

Correct selection

Confirm separately the outside diameter of the 1/2" tube and the 15 mm hose connection. 12.7 mm and 15 mm must not be treated as equivalent sizes.

Practical applications

It can be used in compatible dispensing, water, camper, or marine installations when you need to link both types of tubing formats.

Installation

Work with the circuit depressurized. Make straight cuts, avoid ovalization, and connect each side to the corresponding fitting. Once installed, make sure the hose is not exerting leverage or continuous tension on the adapter.

Maintenance

Inspect the condition of the tube and hose at every intervention. If there is a leak, first check that each side matches the indicated size and is correctly inserted or secured.
